In Calexico, Vice President Mike Pence was taking a heavily secured tour of the construction site for a border barrier and talk to local Border Patrol agents about their work and needs.

Meanwhile, a two-hour drive west, a caravan of immigrants who drew the ire of President Trump was waiting at the Tijuana-San Diego border crossing to ask for asylum in a scene marked by emotion and theater.

Air Force Two landed at around 10:30 a.m. at the Naval Air Facility in El Centro. The vice president stepped out of the plane his wife, Karen, and waved to a small crowd of military personnel, some of whom had brought their children to meet him. He shook hands and posed for photos before hopping into a black sport utility vehicle in a long motorcade for the trip to a Border Patrol station.
